Fig. 4From: Elevated levels of matrix metalloproteinases reflect severity and extent of disease in tuberculosis-diabetes co-morbidity and are predominantly reversed following standard anti-tuberculosis or metformin treatmentCirculating MMPs are marker of bacterial burden in TB-DM. The relationship between the plasma levels of MMPs and smear grades as estimated by sputum smears was examined in TB-DM individuals at baseline. The data are represented as scatter plots with each circle representing a single individual. P values were calculated using the Linear trend post – testBack to article page
